Which alarm sound indicates a Standard alarm?

• A. Three short, high beeping alarm sound
• B. Continuous, slow, beeping alarm sound
• C. Continuous, fast beeping alarm sound
• D. No alarm sound

Answer: (B)

Alarm sounds are used to signal different alert levels, so each pattern has a specific meaning. The standard alarm is signaled by a continuous, slow beeping pattern. This keeps attention focused and indicates a general alert without the urgency of higher-priority signals. Fast, continuous beeping is typically reserved for more urgent situations, such as evacuations, while short, rapid bursts or a test pattern denote other conditions. No alarm means everything is normal.

So, the continuous, slow beeping best matches the standard alarm.
